Prokofiev Sonata No. 2

[Pumpkinhead]

Yeah, I'm 16 years old, and i'm taking on the fourth movement. I've played easier stuff like Polichinelle and the Revolutionary Etude. anyhoo, I'm really freaked out on learning this, as well as the Scherzo no. 2 by Chopin. Are there any wiser pianists with some help on either of these to a total amature? Thanks to anyone that does.
